Statistics for alg1

Given a problem consisting of \(m\) subproblems with \(Y_N^s\) given for each subproblem \(s\), we use a filtering algorithm to find \(Y_N\) (alg1).

The following instance/problem groups are generated given:

Status

  • 826/1600 problems have been solved, i.e. 774 remaining.
  • 820/826 problems have 5 instances solved for each configuration.
  • 52/826 have not been classified.
  • 81/826 have not been fully classified (only classified extreme).

Problems solved for the analysis

Note that the width of objective \(i = 1, \ldots p\), \(w_i = [l_i, u_i]\) should be approx. \(10000m\). Check:

Size of \(Y_N\)

What is \(|Y_N|\) given the different methods of generating the set of nondominated points for the subproblems?

## # A tibble: 4 × 3
##   method mean_card     n
##   <chr>      <dbl> <int>
## 1 l         61102.   170

Does \(p\) have an effect?

Nondominated points classification

We classify the nondominated points into, extreme, supported non-extreme and unsupported.
